Accordingly, it should be apparent to those skilled in the art that the following description of various embodiments of the disclosure is provided for illustration purposes only and not for the purpose of limiting the disclosure as defined by the appended claims and their equivalents.

It is to be understood that the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a component surface” includes reference to one or more of such surfaces.

An expression “having”, “may have”, “comprising”, or “may comprise” used in the disclosure indicates presence of corresponding characteristics (e.g., components such as numerical value, function, operation, or element) and does not limit additional at least one function, operation, or element.

In the disclosure disclosed herein, the expressions “A or B”, “at least one of A or/and B”, and “one or more A or/and B” used herein may include any and all combinations of one or more of the associated listed items. For example, “A or B”, “at least one of A and B” or “at least one of A or B” may include all the cases of (1) including at least one A, (2) including at least one B, or (3) including at least one A and at least one B.

Expressions such as “first,” or “second,” and the like, may express their components regardless of their priority or importance and may be used to distinguish one component from another component but is not limited to these components.

When an element (e.g., first element) is referred to as being “(operatively or communicatively) coupled with/to” or “connected to” another (e.g., second) element, it may be directly coupled with/to or connected to the other element or an intervening element (e.g., a third element) may be present. However, when it is described that an element (e.g., first element) is “directly coupled” to another element (e.g., second element), no element (e.g., third element) may exist between the element and the other element.

According to the situation, the expression “configured to (or set to)” used herein may be interchangeably used as, for example, the expression “suitable for”, “having the capacity to”, “designed to”, “adapted to”, “made to”, or “capable of”. The term “configured to” may not necessarily imply “specifically designed to” in hardware. In some situations, the expression “device configured to” may mean that the device, together with other devices or components, “is able to”. For example, a “sub-processor configured to (or set to) perform A, B, and C” may mean a dedicated processor (e.g., an embedded processor) for performing a corresponding operation or a generic-purpose processor (e.g., a central processing unit (CPU) or an application processor) which performs corresponding operations by executing one or more software programs which are stored in a memory device.

When the processor 130 receives a user input for executing the assistant service by executing at least one command stored in the memory 120, the processor 130 may transmit information on the user voice acquired by the electronic apparatus 100 to the plurality of servers 200-1, 200-2, . . . , 200-n providing different assistant services through the communicator 110, and thereafter, when a plurality of response information are received from the plurality of servers 200-1, 200-2, . . . , 200-n, the processor may provide a response on the user voice based on at least one of the plurality of received response information.

A case where the user input for executing the assistant service is received may include a case where a user voice including a wakeup word (or a wakeup command) is input or a case where a user input based on selection of a predetermined button is input.

In this case, the wakeup word refers to a trigger word for executing the assistant service or requesting a response of the assistant service, and the user must utter a wakeup word corresponding to a voice call command to use the assistant service in the electronic apparatus 100. This wakeup word may be determined based on the assistant service. For example, the wakeup word may include a name of an AI used in each company for assistant services. Thus, the wakeup word may be different depending on types of assistant services.

In addition, the wakeup word may be changed according to a user input. The user may access a server through the electronic apparatus 100 or another electronic apparatus (not shown) and change the wakeup word. For example, the user may request to change a wakeup word “Hi Bixby” to “hello Bixby” and the server may register the wakeup word changed according to the user input. However, if all or a part of a new wakeup word input by the user for change is the same as all or a part of a wakeup word of an assistant service provided by another server, the server may reject the user's request for the change and may not change the wakeup word.

The user voice may be input through a microphone (not shown) provided in the electronic apparatus 100 or an external electronic apparatus (not shown) connected to the electronic apparatus 100 may receive a user voice and transmit the received user input to the electronic apparatus 100.

FIG. 2B is a block diagram illustrating a configuration of an electronic apparatus according to an embodiment of the disclosure.

Referring to FIG. 2B, hereinafter, a method of providing a response on a user voice through the plurality of assistant services will be described in detail.

First, a case where a user voice including a specific wakeup word is input as a user input for executing an assistant service according to an embodiment of the disclosure will be described.

When a user input for executing a first assistant service is received, the processor 130 may transmit information on the user voice to a first server providing the first assistant service and a second server providing a second assistant service and transmit a response on the user voice based on the response information received from the first server among the plurality of response information received from the first and second servers.

When a first wakeup word for executing the first assistant service is identified in a first user voice acquired by the electronic apparatus 100, the processor 130 may transmit information on the first user voice to the first server providing the first assistant service and the second server providing the second assistant service, and provide a response on the first user voice based on the response information received from the first server among the plurality of response information received from the first server and the second server based on the transmission of the information on the first user voice.

The processor 130 may determine whether a wakeup word is present in the user voice using a wakeup engine 131. The wakeup engine 131 may include an AI model trained to recognize various wakeup words, in which case the wakeup word may be additionally designated or changed. In FIG. 2B, it is described that the wakeup engine 131 and a voice recognition module 132 are implemented in hardware, but they may be implemented in software, and in this case, may be stored in the memory 120.

The processor 130 may store the input user voice in the memory 120, perform voice recognition on the user voice of a predetermined interval through the wakeup engine 131, and determine whether a wakeup word is present in the user voice.

The wakeup word is a wakeup word for executing any one of a plurality of assistant services provided by the plurality of servers 200-1, 200-2, . . . , 200-n.

Accordingly, when the wakeup word is present in the user voice, the processor 130 may transmit the information on the user voice to the plurality of servers 200-1, 200-2, . . . , 200-n through the communicator 110.

The processor 130 may acquire information on the user voice from the user voice acquired by the electronic apparatus 100.

The processor 130 may generate a voice file or a compressed voice file for the user voice or perform preprocessing on the user voice, and generate a voice file or compressed voice file for the preprocessed user voice. In addition, the processor 130 may extract feature points from the user voice and acquire information on the user voice.

The processor 130 may transmit the information on the user voice excluding the wakeup word from the user voice to the plurality of servers 200-1, 200-2, . . . , 200-n. For example, the processor 130 may transmit information on the user voice present after the wakeup word to the plurality of servers 200-1, 200-2, . . . , 200-n.

To this end, the processor 130 may execute (or launch or activate) applications 121-1, 121-2, . . . , 121-n stored in the memory 120.

The applications 121-1, 121-2, . . . , 121-n, as programs for providing an assistant service function by interworking with each of the plurality of servers 200-1, 200-2, . . . , 200-n, may transmit and receive various types of information for providing the assistant service to and from the plurality of servers 200-1, 200-2, . . . , 200-n and provide a response on a user voice.

These applications 121-1, 121-2, . . . , and 121-n may be downloaded through the plurality of servers 200-1, 200-2, . . . , 200-n or through a separate application store and installed in the electronic apparatus 100 or the electronic apparatus 100 may access the plurality of servers 200-1, 200-2, . . . , 200-n to use a corresponding function according to a cloud service method.

In this case, the processor 130 may execute all other applications 121-2, . . . , 121-n, as well as the application 121-1 for providing the assistant service corresponding to the wakeup word, and transmit the information on the user voice to the plurality of servers 200-1, 200-2, . . . , 200-n through the applications 121-1, 121-2, . . . , 121-n.

Even if a wakeup word for executing a specific assistant service is input, the processor 130 may provide the information on the user voice not only to the server 200-1 providing a specific assistant service but also the servers 200-2, . . . , 200-n different from the corresponding server.

The plurality of servers 200-1, 200-2, . . . , 200-n may generate response information on the user voice based on the information on the user voice received from the electronic apparatus 100 and transmit the response information to the electronic apparatus 100.

When the response information on the user voice is received from the plurality of servers 200-1, 200-2, . . . , 200-n, the processor 130 may provide a response on the user voice based on the response information generated by the assistant service corresponding to the wakeup word among a plurality of response information.

When the user speaks the wakeup word indicating the specific assistant service requests a response of the corresponding assistant service, the processor 130 may provide the response on the user voice based on the response information received from the server providing the assistant service matched to the wakeup word among the plurality of received response information. In this case, the processor 130 may store other response information in the memory 120.

The processor 130 may determine whether a second user voice acquired after the first user voice corresponds to a voice requesting a response result of another assistant service regarding the first user voice.

The processor 130 may determine whether the user voice corresponds to a voice requesting a response result of the other assistant service using the voice recognition module 132.

The voice recognition module 132 may convert the user voice into text by performing voice recognition on the user voice and recognize whether an intent of the user voice requests a response result of the other service based on a voice recognition result. In this case, the speech recognition module 132 may include an AI model trained to determine whether the user voice requests a response result of the other assistant service through natural language understanding.

The processor 130 may perform recognition on the user voice only in a state where the applications 121-1, 121-2, . . . , 121-n are executed, and determine whether the corresponding user voice has an intent of requesting a response result of another assistance service.

Accordingly, when the second user voice does not correspond to a voice requesting a response result of the second assistant service regarding the first user voice, the processor 130 may transmit information on the second user voice to the first server and the second server, and provide a response on the second user voice based on the response information received from the first server among the plurality of response information received from the first server and the second server based on transmission of the second user voice.

When the user utters a voice having a different intent without requesting information provided by another assistant service, the processor 130 provides a response on the user voice afterwards by continuously using the assistant service which has previously provided a response. However, even in this case, the processor 130 also transmits information on the user voice acquired afterwards to the plurality of servers in that a response provided by another assistant service may be requested for a user voice that the user utters afterwards.

When the second user voice corresponds to a voice requesting a response result of the second assistant service for the first user voice, the processor 130 may provide a response on the second user voice based on response information received from the second server providing the second assistant service among a plurality of response information received based on the transmission of the information on the first user voice.

When the user utters a voice requesting information provided by another assistant service with respect to a previous user voice, the processor 130 may provide a response on the user voice based on response information received from a server providing an assistant service requested by the user among a plurality of response information received for the previous user voice.

Meanwhile, when the assistant service is changed according to a user's request, the processor 130 may provide a response on a user voice afterwards using the changed assistant service. The processor 130 may provide a response on the user voice by using the changed assistant service until a user voice requesting a change to another assistant service is input again, and when a user voice requesting a change to another assistant service is input, the processor may provide a response on the user voice using the assistant service requested by the user.

As described above, according to an embodiment of the disclosure, when information on a user voice is transmitted to the plurality of servers and a response on the user voice is provided using a plurality of response information received from the plurality of servers, a plurality of assistant services may be provided to the user seamlessly, and in that the user may be provided with responses from various assistant services, satisfaction and convenience of the user who uses the assistant service may be enhanced.

FIG. 3 is a view illustrating a method of providing an assistant service according to an embodiment of the disclosure.

Referring to FIG. 3, it is assumed that the user utters “XXX, what time is it now?” Here, XXX may be a wakeup word for an assistant service provided by the first server 200-1.

In this case, as shown in {circle around (1)} of FIG. 3, the processor 130 may execute the applications 121-1, 121-2, . . . , 121-n and transmit information on the “What time is it now?” which is the user voice excluding the wakeup word to the plurality of servers 200-1, 200-2, . . . , 200-n through the applications 121-1, 121-2, . . . , 121-n.

Accordingly, as shown in {circle around (2)} of FIG. 3, the plurality of servers 200-1, 200-2, . . . , 200-n may generate response information to “What time is it now” received from the electronic apparatus 100 and transmit the generated response information to the electronic apparatus 100.

For example, the first server 200-1 may transmit “It's 9 o'clock in the morning” as response information to the electronic apparatus 100, and the second server 200-2 may transmit “May I tell you in Korean time?” as response information to the electronic apparatus 100, and the n-th server 200-n may transmit “It's 9 o'clock” as the response information to the electronic apparatus 100.

FIG. 4 is a view illustrating a method of providing an assistant service according to an embodiment of the disclosure.

Referring to FIG. 4, in this case, in that the assistant service (or voice assistant) called by the user is XXX, the processor 130 may display a screen including “It's 9 o'clock in the morning” 410 on a display of the electronic apparatus 100 based on the response information received from the first server 200-1.

FIG. 5 is a view illustrating a method of providing an assistant service according to an embodiment of the disclosure.

Referring to FIG. 5, it is assumed that the user utters “How's the weather today?”.

In this case, the processor 130 determines that “How's the weather today” corresponds to a voice requesting a response result of another assistant service in that the applications 121-1, 121-2, . . . , 121-n are executed. Because “How's the weather today” does not correspond to a voice requesting a response result of another assistant service, the processor 130 may transmit the information on “How's the weather today” which is the user voice to the plurality of servers 200-1, 200-2, . . . , 200-n as shown in {circle around (1)} of FIG. 5.

Accordingly, as shown in {circle around (2)} of FIG. 5, the plurality of servers 200-1, 200-2, . . . , 200-n generates response information to “How's the weather today” received from the electronic apparatus 100 and transmits the generated response information to the electronic apparatus 100.

For example, the first server 200-1 may transmit “it will rain a bit today” as response information to the electronic apparatus 100, the second server 200-2 may transmit “Chance of rain today is 60 percent” as response information to the electronic apparatus 100, and the n-th server 200-n may transmit “For today, weather will be nice but rain is likely between 6 and 7 p.m.” as response information to the electronic apparatus 100.

FIGS. 7A and 7B is a view illustrating a method of providing an assistant service according to various embodiments of the disclosure.

Referring to FIG. 7A, subsequently, when the user utters “YYY, let me know about the result”, the processor 130 may determine whether “YYY, let me know about the result” corresponds to a voice requesting a response result of another assistant service in that the applications 121-1, 121-2, . . . , 121-n are executed. Here, YYY may be a wakeup word for the assistant service provided by the second server 200-2.

Referring to FIG. 7B, since “YYY, let me know about the result” corresponds to a voice requesting a response result of the assistant service YYY, the processor 130 may display a screen including “Chance of rain today is 60 percent” 710 on the display of the electronic apparatus 100 based on the response information on “How's the weather today?” previously received from the second server 200-2 as shown in FIG. 7B.

FIG. 8 is a view illustrating a method of providing an assistant service according to an embodiment of the disclosure.

Referring to FIG. 8, it is assumed that the user utters “Is it still going to rain this weekend?”.

In this case, the processor 130 may determine that “Is it still going to rain this weekend?” corresponds to a voice requesting a response result of another assistant service in that applications 111-1, 111-2, . . . , 111-n are executed. Because “Is it still going to rain this weekend?” does not correspond to a voice requesting a response result of another assistant service, the processor 130 may transmit information on the “Is it still going to rain this weekend?” which is a user voice to the plurality of servers 200-1, 200-2, . . . , 200-n as shown in {circle around (1)} of FIG. 8.

Accordingly, as shown in {circle around (2)} of FIG. 8, the plurality of servers 200-1, 200-2, . . . , 200-n may generate response information on “Is it still going to rain this weekend?” received from the electronic apparatus 100 and transmit the generated response information to the electronic apparatus 100.

In the example described above, the processor 130 may provide a user interface indicating that a response from another assistant service may be provided.

When providing the response of the assistant service called by the user, the processor 130 may display a name of an assistant service other than the assistant service called by the user together with the response of the assistant service called by the user to inform the user that a response of another assistant service may also be provided.

FIG. 10A, 10B, and 10C are views illustrating a method of providing an assistant service according to various embodiments of the disclosure.

Referring to FIG. 10A, when the user utters “XXX, how's the weather today?”, the processor 130 may display “It will rain a bit today” 1010 on the display based on response information provided by the assistant service XXX. In this case, the processor 130 may display YYY 1020 and ZZZ 1030 which are names of other assistant services on the display.

Referring to FIGS. 10B and 10C, Thereafter, when the user utters “YYY, let me know also about the result” as shown in FIG. 10B, the processor 130 may display “Chance of rain today is 60 percent” 1040 on the display as shown in FIG. 10C based on the response information received from the server providing the assistant service YYY. In this case, the processor 130 may display XXX 1050 and ZZZ 1030, which are the names of the other assistant services, on the display.

A case where a user input for selecting a predetermined button is input as a user input to execute an assistant service will be described.

When a user voice is acquired after a user input based on selection of a predetermined button is received, the processor 130 may transmit the information on the user voice to the plurality of servers 200-1, 200-2, . . . , 200-n.

The predetermined button is a button for triggering an assistant service. When the predetermined button is selected, the processor 130 may execute the applications 121-1, 121-2, . . . , 121-n stored in the memory 120 and transmit information on a user voice input afterwards to the plurality of servers 200-1, 200-2, . . . , 200 through the applications 121-1, 121-2, . . . , 121-n.

The predetermined button may be provided in the electronic apparatus 100 or in an external electronic apparatus (not shown) connected to the electronic apparatus 100. In this case, when the predetermined button is pressed, the external electronic apparatus may transmit a signal indicating that the predetermined button was pressed to the electronic apparatus 100.

The plurality of servers 200-1, 200-2, . . . , 200-n generate response information regarding the user voice received from the electronic apparatus 100 and transmit the response information to the electronic apparatus 100.

When the response information for the user voice is received from the plurality of servers 200-1, 200-2, . . . , 200-n, the processor 130 may provide a plurality of responses for the user voice based on the plurality of response information.

When the user does not request a response by specifying an assistant service as if the user uttered a specific wakeup word, the processor 130 may provide a response on the user voice based on the plurality of response information provided from the plurality of assistant services.

In this case, the processor 130 may provide the plurality of responses in different forms based on at least one of a user preference for the plurality of assistant services provided by the plurality of servers and accuracy of the plurality of response information.

The processor 130 may display a response of the assistant service having the highest user preference to be the largest, display the response in a color different from those of other assistant services or highlight the response based on the user preference on the plurality of assistant services provided by the plurality of servers. Alternatively, the processor 130 may display a response of the assistant service having the highest user preference and display only names of other assistant services. The processor 130 may display the response of the assistant service in order of high user preference. When displaying the responses of the plurality of assistant services, the processor 130 may display them in order of user preference.

The processor 130 may store the information on the assistant service used by the user in the memory 120 and update the corresponding information every time the user uses the assistant service.

Accordingly, the processor 130 may determine that the user has a high preference in order of the assistant services, starting from an assistant service having the highest use frequency of the user.

The processor 130 may display a response of an assistant service that does not provide an accurate response to be smaller than a response of other assistant services, display only a name of the assistant service, or display only the name of the assistant service or only a portion of the response based on accuracy of the plurality of assistant services provided by the plurality of servers.

For example, in case where it is not possible to analyze a meaning of a user voice, the plurality of servers 200-1, 200-2, . . . , 200-n may not configure response information. In this case, the plurality of servers 200-1, 200-2, . . . , 200-n may transmit response information such as “the service is not supported” to the electronic apparatus 100.

The processor 130 may determine that the assistant service provided by the corresponding server does not provide an accurate response on the user voice, and may display the response of the assistant service to be differentiated from that of other assistant services.

After providing a plurality of responses, when a user voice is input, the processor 130 may determine whether a wakeup word is present in the user voice using the wakeup engine 131.

Accordingly, when the wakeup word is not present, the processor 130 may transmit the information on the user voice to the plurality of servers 200-1, 200-2, . . . , 200-n and provide a plurality of responses based on a plurality of response information received from the plurality of servers 200-1, 200-2, . . . , 200-n. In this case, the processor 130 may differentially display the plurality of responses as described above.

However, when the wakeup word is present, the processor 130 may transmit information on the remaining portion of the user voice excluding the wakeup word to the plurality of servers 200-1, 200-2, . . . , 200-n.

When the response information on the user voice is received from the plurality of servers 200-1, 200-2, . . . , 200-n, the processor 130 may provide a response on the user voice based on response information generated by the assistance service corresponding to the wakeup word among the plurality of response information.

After the user utters a wakeup word indicating a specific assistant service, responses of a plurality of assistant services are not provided but a response on the user voice may be provided based on response information received from a server providing the assistant service for which the user has requested a response, that is, the assistant service matched to the wakeup word. In this case, the processor 130 may store other response information in the memory 120, and thereafter, when a response result of the other assistant service is requested, the processor 130 may provide a response using the response information stored in the memory 120.

A specific operation of the processor 130 in case where the wakeup word is present in the voice uttered by the user is the same as described above, and thus a detailed description thereof will be omitted.
